I've read both that Iodine fixes hypothyroid in large doses, and that it can cause hypothyroid in large doses by supressing thyroid function.
Personally I've cycled on and off Iodine many times and always seem to feel better with more consistent energy when I'm on it.

WRONG! It totally depends on WHY your thyroid isn't working! If you simply have a sluggish thyroid, resulting in a hypothyroid condition, than yes you can supplement with iodine. HOWEVER, if you have an AUTOIMMUNE disease such as Hashimotos, then NEVER supplement with iodine. In autoimmune conditions that attack your thyroid gland, additional iodine will make your disease WORSE. Get diagnosed as to why your thyroid isn't working.

Increased iodine can only increase thyroid function, not decrease it. THERE IS NO U-SHAPED CURVE association between iodide and thyroid function, that is pure bullshit. Too little iodine causes HYPOthyroidism, too much causes HYPERthyroidism, these two conditions are complete opposites, it's as simple as that. If you consume normal, plain old iodized table salt you have nothing to worry about.

Both are correct.
Most nutrients have a U-shaped curved. If you're at the ends, you'll either be deficient, or overdosing, (i.e. a total absence of iodine on one end, or far too much at the other end). The middle of the U is where you want to be, that's where the nutrient provides the most benefit and is optimal.
Turns out that iodine need depends on your body's individual need. The USRDA is far too low to be optimal, and is only the absolute minimum needed to avoid goiters - even then with the "War on Salt" and people switching to seasalt over iodized salt, you could easily get too little.
Modern life is full of halogens (chlorine, bromides, fire retardants in furniture, etc) and other endocrine system disruptors that get mistaken for iodine by the receptors and block iodine from entering. So we actually need even more than in the past.
If you take a large load of iodine to displace the halogens, it may work (and you may experience symptomps such as diarhea), but if you continue, you may cause problems.
Something like 2-5 drops of Lugol's Solution at 2% is plenty for loading. Don't do that every day.
You should always take iodine with selenium as both minerals are needed to produce the thyroid hormones.
